EPA's action plan for United Heckathorn cleanup along the Richmond Channel in northern California relies on use of passive samplers to identify areas of sediment contaminated by DDT.
Cleanup at the Rainbow Valley Citrus Maintenance Yard Facility in Goodyear, Arizona, recently involved air sparging to address contamination from leaking underground storage tanks. Associated vapors were collected through solar-powered fans designed to also capture passive wind energy that vented monitoring wells with high hydrocarbon concentrations. Use of renewable energy instead of grid-supplied power otherwise needed to operate a conventional air blower avoided consumption of approximately 20,000 kWh of electricity and emission of over 18 metric tons of carbon dioxide equivalent while lowering project costs over 10 months of air sparging.

Incorporating Sustainable Environmental Practices into Remediation of Contaminated Sites
- EPA Strategic Plan, FY 2014-2018
- ...EPA's hazardous waste programs also are working to reduce the energy use and environmental footprint during the investigation and remediation of hazardous waste sites.
Goal 3: Cleaning Up Communities and Advancing Sustainable Development
EPA's Methodology for Understanding and Reducing a Project's Environmental Footprint uses 21 metrics and a seven-step process to quantify energy, air, water, and materials & waste comprising the environmental footprint of a remedy. The supporting Spreadsheets for Environmental Footprint Analysis (SEFA) workbooks are available to help users estimate each of the methodology's metrics on a site-specific basis. Related background studies, examples, and data gathering tools offer additional information of value to environmental footprint assessment.
